Families who are travelling with children represent one of the biggest markets in tourism industry. When planning a trip, parents focus primarly on the needs of their children, which leads them to choose accomodation that is suitable for families. Those hotels should offer facilities which will be interesting for the whole family. The aim of this work is to determine level of influence that children have on family decisions, related to the choice of hotel for vacation, to identify factors that parents consider important in that selection and to understand what are the specific needs of families with children when choosing hotel for vacation. The survey questionnaire was conducted on a sample of 116 parents via social networks. The results show that children have the greatest degree of influence on creating parents' motivation to go on vacation and on making family decision in stage of expressing desire and need to go on vacation. When choosing components of a hotel vacation, children have the greatest influence on the choice of activities, but wives mostly have the autonomy. The wife is dominant in all stages of the process of making a decision about choosing a hotel. Factors that parents consider important when making that choice are safety and location of the hotel. In order for the hotel to meet the specific needs of families with children, the most important thing is that it provides safety standars, high level of hygiene, that it offers activities for children and that it takes care of their nutritional needs. Research results can contribute to a better understanding of how hotels can alter their offer and marketing activities in order to attract and meet the expectations of this target segment more efficient. Consideration of the needs of parents and children affects not only the increase in the number of visitors, but also the increase in consumption and sales in the future.
